Question

Терміново!!! М’яч кинули вертикально вгору з початковою швидкістю 15 м/с. Визначте швидкість руху м’яча через 0,5 с після початку руху.

Answer 1

Ответ: 10м/с

Объяснение:

Дано:

Vo=15м/с

t=0,5с

--------------

V-?

V=Vo-gt=15-10*0,5=10м/с

Answer 2

Calculating the Velocity of the Ball

To calculate the velocity of the ball after 0.5 seconds, we can use the following kinematic equation:

v = u + at

Where: - v = final velocity - u = initial velocity - a = acceleration - t = time

Given: - Initial velocity (u) = 15 m/s (upward) - Time (t) = 0.5 s - Acceleration (a) = acceleration due to gravity (approximately -9.81 m/s^2, considering the direction)

Substitute the given values into the equation to find the final velocity:

v = 15 m/s + (-9.81 m/s^2 * 0.5 s)

v ≈ 15 m/s - 4.905 m/s ≈ 10.095 m/s

So, the velocity of the ball after 0.5 seconds is approximately 10.095 m/s upward.
